I know shot placement and distance of shot are all factors in saying yes or no to bullet caliber, but under 400 yards with good shot placement and a quality bullet, would either of these calibers be enough to safely get the job done? Want to socut this summer for a fall bear

Great now I just need to find one of those critters. that's my summer scouting mission. Looking forward to learning about bear habitat. Seen a few on accident on hother hunts but have a ton to learn, at least I don't have to worry about my rifle
